No. Alpha radiation is helium nuclei, 24He2+, so there is mass (4 AMU) along with the energy (velocity).
The radiation that is most commonly associated with energy is the gamma or x-ray, consisting of photons emitted from the nucleus or electron cloud, respectively. Even then, there is mass, even though small, and even though the rest mass of a photon is zero, because energy is equivalent to mass1 times the velocity of light squared. (e = mc2) As a result, energy cannot exist without mass, nor can mass exist without energy, but that is a little bit out of scope for this question.
Suffice to say that there is no such thing as pure energy - you also need mass, but for the purposes of this question, alpha is not pure energy - not by a long shot.
1Careful - do not misunderstand that energy and mass can be converted into each other. This is a common error based on not understanding what e = mc2 means. The truth is that energy is mass, and massis energy, and neither can be created nor destroyed - they can only be moved around from one frame of reference to another.

Is Alpha Beta or gamma made from electrons?
Beta radiation is made from electrons (or positrons for inverse beta radiation). Alpha radiation is a helium nucleus, and gamma radiation is a high energy electromagnetic ray.
Is alpha radiation a ionization radiation?
Yes, alpha radiation is an ionizing radiation.
What is radioactivity and what is the difference between alpha beta and gamma radiation?
Alpha radiation is helium-4 nuclei - i.e., each alpha particle consists of 2 protons and 2 neutrons.Beta radiation is either electrons or positrons (= anti-electrons). Gamma radiation is high-energy photons.
How is EM radiation different from alpha and beta radiation?
EM radiation is essentially high energy light, with wavelengths ranging from 10 nanometers low energy x rays to 10 picometers high energy gamma rays. Beta radiation refers to high speed electrons while an alpha ray is a high speed proton.
Alpha is it ionizing?
Yes, alpha radiation is an ionizing radiation.
Which radiation gets rid of its energy quickest?
alpha radiation
Which type of radiation has no mass or charge?
Free radiation I suppose. But gamma radiation, is charge free. As is UV, IR, ... ..
What type of radiation does radium give off?
Radium emits alpha, beta, and gamma radiation. Alpha radiation is fully ionized helium nuclei. Beta radiation is high energy electrons. Gamma radiation is very high energy electromagnetic radiation. All of these can do significant damage to living things.
What is the radiation?
what is the meaning radition? radiation is a by product of nuclear energy which can be in the form of alpha,beta and gramma rays.radioisotopes emit radiation.
Which form of nuclear radiation is a form of energy?
All forms of nuclear radiation, including alpha, gamma, beta, neutron, are forms of energy.
Is Alpha Beta or gamma made from electrons?
Beta radiation is made from electrons (or positrons for inverse beta radiation). Alpha radiation is a helium nucleus, and gamma radiation is a high energy electromagnetic ray.

This nuclear energy is pure energy not made of any particle?
Gamma radiation

Which type of radiation alpha beta or gamma results in the greatest change in mass number?
alpha - 2 neutrons and 2 protons released or neutron collision with a fissionable nucleus resulting in the fissioning of the atom into two fission fragments and more neutrons creating two atoms each a little less than half the atomic mass of the original atom
